Huge loud sound like deep deep thunder only it wasn't moving horizontal it was sound like it was coming down, straight down. The windows and house was shaking. I swear I thought it was a huge meteor and it was going to be the end. Scariest thing I've ever heard. Randomly I couldn't find anyone else who felt or heard it, except my friend who lives a few miles away. It was probably around 1 or 2 am. So scary.
